Abstract: IMPROVED SELF-PROPELLED CROP HARVESTER       Abstract of the Disclosure A self-propelled crop harvester has opposite upright frame sides in truss form with horizontal frame members extending be-tween them.  A grain tank in saddle configuration straddles crop processing means and an engine, and sections of the walls of the saddle portions of the tank serve as the center bays of the truss frame sides.  The saddle portions of the tank are also structurally connected at their lower extremities to the housing of a transverse auger conveyor which transfers grain from one saddle portion of the tank to the other.  In addition to its conveyor function, the housing serves as a horizontal frame member.  The transverse conveyor housing, and the front and rear axle assemblies which interconnect the frame sides at their forward and rearward ends respectively, all have substan-tial torsion strength.  The principal functional units of the harvester are self contained, and pinned joints are used to facilitate their assembly to and removal from the harvester as modular units.

Abstract: Case 2316 ABSTRACT OF THE DISCLOSURE           It is desirable to be able to detect an emergency shutdown or "trip" of a process by independent means, that is without receiving a signal from the control means that initiates the trip.  This is the case, for example, in a nuclear reaction process.  The independent trip detection of this invention determines the rate of change of a parameter representative of the state of the process and provides a signal representing the rate of change.  The signal is compared with a reference and if (a) the parameter has changed by a predetermined amount and (b) the rate of change has exceeded a predetermined level continuously for a period of time consistent with a process trip, then an output signal is provided indicative of a process trip having occurred.

Abstract: PROCESS FOR ALKALI COOKING AND DELIGNIFYING CELLULOSIC MATERIALS                              ABSTRACT               A process for alkali cooking and delignifying cellulosic materials by using a vertical type pressurized reaction vessel providing therein with an alkali cooking zone, a washing zone, and a liquor-dis-placement delignifying zone in that order from one end to the other end of the reaction vessel. Chip-form cellulosic raw materials are cooked in the alkali cooking zone by an alkali cooking liquor and then washed in the washing zone. The thus cooked and washed cellulosic materials are transferred to the delignifying, zone where they are contacted with an alkaline aqueous medium containing previously dissolved oxygen to pro-ceed delignification with oxygen. A part of waste liquor formed during delignification is continuously discharged from the delignifying zone, while the fresh alkaline aqueous medium containing dissolved oxygen is continuously charged into the delignifying zone, whereby the continuous displacement of the waste liquor with the fresh alkaline aqueous medium containing dissolved oxygen is carried out in the liquor-displacement delignifying zone.

Abstract: IMPROVED WRITING AND ERASING IN AC PLASMA DISPLAYS                 Abstract Improved writing and erasing in AC gas discharge display panels is obtained by applying a special normalizing voltage waveform to cause the cells to be in a more standardized state, so that the applied writing and erasing pulses act to cause wall voltage changes which are less sensitive to the cell's recent history.  The special normalizing waveform is applied adjacent to the erase pulse and/or  to the write pulse and acts to fire the cells in a manner such that there is no loss in the memory state of the cells.
